Abstract: A battery pack which is disposed under a floor of a vehicle includes a plurality of battery cells, and a battery case which accommodates the plurality of battery cells, in which the battery case includes a fixing portion to which a portion of a suspension of the vehicle is fixed.

Abstract: The disclosure provides a battery case structure. The battery case structure includes a battery provided below a floor panel of a vehicle, a lower case covering the battery from below, and an upper case including a horizontal plate portion arranged between the floor panel and the battery and covering the battery from above. The thickness of the outer peripheral portion of the horizontal plate portion in the upper case along the vertical direction is thicker than the thickness of the inner peripheral portion of the horizontal plate portion along the vertical direction. The upper case is formed in a plate shape by a metal material, and a plate-shaped reinforcing member is attached to the outer peripheral portion.

Abstract: A battery pack includes a first battery module, a second battery module, and a connector. The first battery module includes laminated cells and has a first outer surface. The second battery module includes laminated cells and has a second outer surface. The second battery module is provided adjacent to the first battery module. The connector has a plane surface and is provided on the first battery module and the second battery module such that the plane surface of the connector opposes the first outer surface and the second outer surface to connect the first battery module and the second battery module.

Abstract: A side sill structure included in a substructure of a vehicle body, includes a battery pack disposed below a floor panel, a side sill disposed at an outer part in a vehicle width direction and extending in a front-rear direction of the vehicle body, and a stiffener disposed inside a cross section of the side sill and extending along an extending direction of the side sill. The stiffener is composed of an outer stiffener bulging outward in the vehicle width direction, and an inner stiffener bulging inward in the vehicle width direction. In the side sill structure, a first side surface of the stiffener, formed on the inner stiffener, is shifted to a relatively upper side than a second side surface of the stiffener, formed on the outer stiffener, and the battery pack is supported on a lower surface of the side sill.

Abstract: An object of the present invention is to provide a vehicle body bottom structure capable of more reliably protecting a battery pack at a time of a side collision of a vehicle. A vehicle body bottom structure of the present invention includes a battery pack disposed below a floor panel, a side sill extending in a vehicle front-rear direction outside in a vehicle width direction and a battery side frame allowing the side sill to support the battery pack, wherein the battery side frame has a lower surface positioned outside in the vehicle width direction and positioned lower than a support portion for the battery pack, the support portion being formed inside in the vehicle width direction of the battery side frame.

Abstract: In a vehicle body framework structure, a closed cross-section frame portion is formed by welding a first outer panel and a second outer panel, and an inner panel is arranged in a closed cross section of the closed cross-section frame portion. An upper joint piece of the inner panel is joined to a first wall portion of the first outer panel by spot welding, and a foaming adhesive material is temporarily fixed to a second wall portion of the second outer panel. When the foaming adhesive material is foamed, a foaming adhesive portion of the foamed foaming adhesive material adheres a lower joint piece of the inner panel and the second wall portion of the second outer panel.
